The state of reacting to all things like a bitch for a determined period of time. Like autopilot, except instead of flying a plane without thinking about it, it's being a bitch without thinking about it.

I did crappy on my bio final, my boyfriend is a jag, and I just got my period. As a result, I'm going to be on autobitch for the rest of May.

A word used in Counter-Strike to define a player who constantly uses either the Terrorist H&K G3/SG-1 or the Counter-Terrorist SG-550 Automatic Sniper Rifles, because of the complete lack of skill involved in wielding them.
